Question

ma 7,725 și 3,804
ma 4,207 și 35,46
[25:4+(3-0,54:0,6) la puterea a 2 ] ×10
[(0,08×7,5+0,7) la puterea a 2 + 14:8] :10 repede va rog

Answer 1

ma=(7,725+3,804):2=11,529:2=5,7645
ma=(4,207+35,46):2=39,667:2=19,8335 

[25:4+(3-0,54:0,6)² ] ×10=
[25:4+(3-0,9)² ] ×10=
[25:4+(2,1)² ] ×10=
(6,25+4,41) ×10=
10,66x10=106,6

[(0,08×7,5+0,7)² + 14:8] :10=
[(0,6+0,7)² + 1,75] :10=
[(1,3)² + 1,75] :10=
(1,69 + 1,75) :10=
3,44:10=0,344
